output of strings and numbers into a single cout statement. We did this for four of the cout statements. That’s acceptable, as long as you string them together with the << signs between each of them. You have access to all the usual goodies with both the division (/) and remainder (%) operators. For example, you can store the quotient in another variable, as you can with the remainder: myQuotient = first / second; myRemainder = first % second; And you have shortcuts available: int first = 30;
default, cin reads in characters from the console based on spaces. If you put spaces in your entry, only the first word gets read. cin reads the second word the next time the application encounters a cin >>. www.it-ebooks.info Chapter 4: Directing the Application Flow In This Chapter ✓ Comparing numbers and evaluating other conditions ✓ Doing things based on a comparison ✓ Repeating code a certain number of times ✓ Repeating code while certain things are true ✓ Repeating code that repeats
the shortcut -> notation to call the string functions. And don’t dereference anything. There are no pointers. Just type the dot (or period) and the function. No asterisks needed. If you write a function that uses a reference and somebody else uses your function in code (see Book I, Chapter 6, for information on how to do this), you could end up making that other person angry. The other person may not realize that, “Hey, man — this thing just messed up my variable!” WHAM! The variable gets
